Best for
  • Users of AI coding tools who need full discussion/documentation context rather than just URLs
  • Clients that support MCP, such as Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and Claude Desktop
  • Teams deploying a remote MCP service via Docker and Streamable HTTP
  • Environments that must egress through a proxy (HTTP/SOCKS5)
  • Engineering teams scaling AI coding agents while controlling spend
  • Platform teams that need auditable, rollback-aware agent execution records
  • Organizations using multiple agents (Claude, Codex, Gemini) under one governed flow
Not for
  • Users who cannot install a Chromium-based browser on the MCP client machine and mainly need arbitrary-site page_content extraction
  • Users who want to expose the remote HTTP port directly to the public internet (it is unauthenticated and unencrypted by default)
  • Users unwilling to provide any search provider API key
  • Developers who just want a simple code-completion helper without run governance
  • Teams unwilling to accept local JSONL run records with HMAC signing
  • Environments without a supported adapter (Claude/Codex/Gemini CLIs, direct provider, or verifier-only)
Required permissions
  • Reads a search provider API key from the environment (one of Serper/SerpBase/Tavily/SearXNG/Sofya/You.com)
  • Optional GITHUB_TOKEN (can be read-only and limited to public repositories) for GitHub Issues/Discussions extraction
  • Launches a local headless Chromium browser process to fetch arbitrary web pages
  • Optional outbound network access via proxy env vars (HTTP_PROXY/HTTPS_PROXY/ALL_PROXY) or KINDLY_CHROME_PROXY
  • Read/write access to the configured repo root (writable scope restrictable via --allow-path/--deny-path)
  • Ability to invoke the chosen agent CLI (Claude/Codex/Gemini, etc.) and its underlying model account
  • Local disk writes for run records, receipts, and share outputs (share/run-receipt., etc.)
  • Execution of user-configured verifier commands (e.g. npm test)
Risks and side effects
  • HTTP transports are unauthenticated and unencrypted by default; exposing the port publicly is risky
  • get_content fetches any URL it is given and runs from the server's network location, which can reach internal resources
  • Browser reuse shares cookies, local storage, cache and user-agent state across requests
  • API keys stored in client config files may leak
  • Failed or timed-out fetches may return partial content or an error message
  • Verifier commands are executed; poorly chosen verifier commands carry security risk despite preflight policy checks
  • Cost and token figures may be estimates (labeled with provenance) and should not be treated as settled accounting
  • Receipt integrity must be verified before use as trustworthy evidence; missing rollback evidence is flagged as EVIDENCE_BOUNDARY
  • Policy defaults come from martin.config.yaml and can be overridden by CLI flags; misconfiguration can loosen safety boundaries
